BWX Technologies (BWXT) a nuclear manufacturing and engineering company that supplies critical components to SMR developers and operates its own advanced reactor designs.
Primary Business: BWXT is best known as the primary supplier of nuclear reactors and fuel for the U.S. Navy and a major manufacturer of nuclear steam generators and heavy components for commercial nuclear plants.
SMR Supply Chain Role: The company is a key supplier in the SMR supply chain, having been selected by GE Vernova Hitachi to manufacture the reactor pressure vessel for the BWRX-300 SMR and signing agreements with Rolls-Royce SMR to design and manufacture nuclear steam generators.
BWXT was selected on August 26, 2026 as one of five contractors for the U.S. Army's Project Janus, deploying its BANR (BWXT Advanced Nuclear Reactor) — a 20 MWe, gas-cooled, TRISO-fueled microreactor — at Fort Campbell, Kentucky.
BWX Technologies has received several analyst upgrades in recent weeks:
Guggenheim upgraded BWXT to Strong Buy on September 15, 2026 (most recent).
Jefferies upgraded to Strong Buy on September 4.
Wells Fargo upgraded from Underweight to Equal Weight on August 27, following the company's Investor Day.
Seaport Global upgraded from Neutral to Buy ($245 PT) on June 22.
Deutsche Bank upgraded from Hold to Buy ($255 PT) on May 15
